The CP11 handheld instrument evaluates the quality of air with a combined measurement of CO2, humidity and temperature. A high concentration of carbon dioxide can develop quickly when closed areas with deficient ventilation are filled with people. Carbondioxide (CO2) is a colorless and odorless gas that exists in the earths atmosphere and which is dangerous in high concentrations.The proportion of CO2in natural ambient air is about 0.04 % or 400 ppm. When humans and animals exhale this gas, it mixes quicklywith the ambient air. A high CO2 content becomes apparent in humans through rapid fatigue and loss of concentration. In order to initiate suitable countermeasures such as an increase in the supply of fresh air, it is important to measure not only parameters such as relative humidity and temperature, but also the CO2 content.
